LED Thermometer with LM35 & LM3914 - PCB Tutorial

■ JLCPCB Prototype for $2(Any Color): https://jlcpcb.com This is a wide range LED Thermometer, it can be used for measuring temperatures between 0 and 150°C Celsius! - The sensor that mounts is an LM35 while driving the LEDs is an LM3914, all with a five color scale. As you can see the in the circuit diagram, output of the LM35 is connected to the input of the LM3914, and there is also a 47K trimmer through which to make small adjustments of the instrument. The LM35 output is a voltage signal (V+) and varies with temperature variation, directly calibrated in °C Celsius. After trying the excellent service offered by JLCPCB I recommend it, the quality of the PCB is high, customer service is always available and professional, the time of realization is short and the delivery of PCBs is by express courier. JLCPCB is a great place to get hight quality custom circuit boards at an extremely low price, you can buy 5 PCB Boards (Any Color) for 2$ !!!
